Why don't we ever see Latino families in the movies? All the other American ethnic groups have given us movies about their march through the generations, but Latinos, until now, have been represented mostly by crime movies and comedies, neither presenting their culture in an especially positive light. A Chicano I know went to see "American Me," a film by Edward James Olmos that is brave and powerful but unremitting in its portrait of a man destroyed by prison, and came out saying, "If I wasn't Chicano, this movie wouldn't have made me want to know any."
